Urinary incontinence (UI) symptoms are highly prevalent among women, and menopause is one of the risk factors for UI. During the menopausal transition, not only the hormonal secretion is changed but also the level of physical activity is affected. The time spent on physical activity is reduced in postmenopausal women. Studies have shown that physical activity acts in a bidirectional manner, exerting either a preventive or an aggravating effect on urinary incontinence. Individuals with sedentary lifestyle and insufficient physical activity (< 150 min/week) are at risk of developing UI, and regular physical activity exerts a protective effect in preventing UI, but the optimal type, duration, and intensity of exercise for the female older adult population remain unknown. In addition, objective measurements of pelvic floor muscle function is needed as the use of self-reported measures may cause response bias. The aim of the study is to investigate the effect of different intensity of exercise on pelvic floor muscle function and HRQoL in postmenopausal women with UI. The investigators hypothesize that (a) both high- and low-intensity physical activities can improve pelvic floor muscle strength and HRQoL in postmenopausal women with UI, and (b) the improvement in high-intensity group is higher than that in low-intensity group. A randomized trial will be conducted to compare the effect of different exercise intensity on pelvic floor muscle function in postmenopausal women with urinary incontinence (n=90).
